*TO ALL WHOM I'l MAY CONOERN:

Be it known that I, EDWARD A. MUCKLE, of the city'and county of Philadelphia, and State of- Pennsyl- Vania, have invented new and luseful Improvements in Watches; and I do hereby declare the following to be a clear and exact description of the nature thereof, suiiicient to enable others skilled in the art to which it appertains to fully understand and use the same, reference being had to the,accompanying-drawings, making part of this specification, in which- Figure I is an elevation showing the opened backs and the rotating inside case. f

.Figures 2 and Sare sectional views illustrating the operations of the spring and pusher and the pendantof the inside case.

My invention is intended to be applied tothatclass of watches generally known as magic-case watches, andlconsists in turning the inside case directly by the pendant of the watch.

It further consists in the construction and arrangement of the pusher,whereby the spring can readily be operated, and the inside case be turned, without the parts interfering with each other, all as will be hereinafter more fully described.

In the drawings, A represents -a watch-case, consisting of the centre B, and backs C and D, one of which is adapted for a hunting-case, and the other the open face. E is the inside case, containing the working parts of the watch, and having the ordinary dial-plate, hands, die. F represents the pendant, placed, as is ordinary, ata point opposite the hinges of the back, and through which passes the pusher G, operating the spring H, which holds the hunting-case back C in a closed position. The pendant F is not Jiirmly secured to the centre B, but is journalled in an opening therein, and thus is capable of being rotated. Its inner end is rigidly attached to the inside case E, audit is therefore evident that the two will move together. The inside ease is also pivoted to the centre B at the point directly opposite to the pendant, and this, with the pendant, forms its axes. The face oi' the watch can quickly bc turned to suit the hunting-case or zopen face by merely openingthe backs, and then turning thetpendant;

The simplicity of the device is apparent. It will materially lessen the expense of magic cases, and adapt them to be introduced into general use.

The pusherG- doesnot'pass entirely through the pendant, but is so constructed as tobe above the end thereof. For this purpose I intend to run the pusher obliquely through the pendant, so that the former will protrude 'at the side of the latter. The spring is placed between the centre B and the inside case E, and isv cut away to allow the pendant to pass through it. The pusher,iwhen depressed will 'bear against the spring, and release the back therefrom, as ordinarily, yet at all times allow the uninterrupted rotation of the inside case, and without th'e parts interfering with each other. Instead of the oblique position of the pusher, it may be placed in-the side of the pendant, or the pendant mayY have its inner end contracted to form a shoulder, through which the pusher may protrude, or it may play in a suitable groove; but in either case the end of thepeudant is to be secured to the inner case, and the spring to be between the Aend of thepusher and the inner case. v

In the ordinary magic cases, the pusher passes entirely through the pendant, and the latter is firmly secured to the centre. -The pusher will operate the spring, irrespective of the position ofthe inside case. This part of my invention is likewise simple.v

As a modiiication, the pendant could be detached from the inside case, and have a toothed wheel at its i-nner end, which would gear or mesh with a corresponding one on the inner case. In this, the operation would be the same as that already described.

The entire device is practical and useful, and can -be manufactured by the ordinary tools now in use.

-Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The inside case E, rotated by the pendant F, substantially as described.

2. 'I he pendant F, journalled in the centre B, and having secured to it the rotating inside case E, sul stantially as and for the purpose described.

3. The pusher Gr, protruding at the side ofthe pendant F, above its end, substantially as described for the purpose specied.

To the above I have signed my name, this fifth day of September, 1867.
